Shiga toxin-producing Escherichia coli (STEC) bacteria, including the Escherichia coli O157, are described as pathogens producing toxin-like Stx 1 and Stx 2. These toxins become a significant virulence factor with a vital role in the outbreak of foodborne diseases worldwide. This study therefore aims to compile articles on STEC in several countries, using systematic review methods. Method : An online database on PubMed was accessed on 29 th October, 2020, to carry out the review, using STEC, E. coli O157, PCR, Stx 1, and Stx 2 as the keywords. This review utilized only full articles, written in English, and published within the past five years. Results : According to the results, there are nine related articles on this topic. In addition, primary E. coli O157 was found to produce toxins and greatly influence the pathogen's meat detection. All STEC strains were positive for Stx 1 , while PCR detected Stx2, and the whole-genome sequencing (WGS) provided forensic-level microbiological cross-contamination links from raw to ready-to-eat meat. Also, most of the articles showed cross-contamination occurred due to E . coli O157 bacteria's movement from the gastrointestinal tract to carcasses, and hygiene, as well as sanitation levels are the biggest causes of this contamination. Conclusion : E . coli O157 was identified not only on food like meat and spinach but also on non-food, including the environment. Improving hygiene and sanitation is a possible way to reduce the contamination of E . coli O157 on meat.

We address the problem of detecting areas with markedly high values (hotspots) in spatial lattice data. Spatial lattice data are observations that include several spatial areas supplemented by neighboring information. The spatial scan statistics is an effective tool for hotspot detection. Echelon analysis is an analytical method to investigate the phase-structure of spatial data both systematically and objectively. In this paper, we describe the structure of spatial lattice data using echelon analysis and detect hotspots based on the echelon structure. As an application, we apply this method to simulation data of leachate accidents in final-disposal sites and detect considerably high-density pollution areas.

Batch studies on anaerobic digestion were performed in 100ml bench top digesters (serum bottles) with solid wastes (limed fleshing) generated from tannery and primary sludge from effluent treatment plant of tannery liquid waste. Digestion was carried out under mesophilic condition. Batch reactors were run at two different organic loading rates. Gas production was higher in test reactor 1 (volatile solids load of 51.9 g/l) than test reactor 2 (volatile solids load of 15.8 g/l). VFA concentration in test reactors 1 and 2 had reduced by 11,970 mg/l (43%) and 2115 mg/l (28.4%) respectively. As biodegradability fraction present in the tannery solid wastes was lower, lag time for the onset of maximum gas production was longer. Based on experimental observation it is concluded that it is more appropriate to evaluate biomethanation potential of solid wastes in terms of biodegradable fraction of volatile solids present in the wastes.

had the surface soil removed and replaced by sandy soil . The cattle manure compost was used to improve soil fertility. The objectives of this study were to determine the effects of cattle manure compost application at rates of 0 (control), 10, 20 and 40 t ha - 1 on rice yields and on 137 Cs transfer to stems, leaves and panicles of rice in 2015. Results showed that rice yields were increased with rates of cattle manure compost. Application of cattle manure compost caused the increase of exchangeable potassium (K) in the soil, resulting in reduction of 137 Cs in rice parts. The 137 Cs concentration was higher in stems than in leaves and was not detected in panicles . The 137 Cs concentration in the aboveground parts of rice was decreased to the lowest (TF = 0 . 009) in soil that received 20 t ha - 1 of cattle manure compost, which was 2 . 4 times lower than that in the control . The transfer factor of 137 Cs (TF) in aboveground parts of rice was negatively correlated with exchangeable K in the soil . The ratio of 137 Cs / K was higher in stems than in leaves and that was related to the concentration of exchangeable Ca, and Mg in the soil . The results indicated that exchangeable K, Ca and Mg derived from cattle manure compost affected the uptake and distribution of 137 Cs in rice plants .

In this study, expanded constellation and expanded kanji graphs are proposed and the effectiveness of these graphs in the multivariate analysis is examined. To draw the expanded constellation graph, the variables are first placed on the circumference of the semicircle using factor loadings. Then, a line is drawn inside the semicircle by connecting the vectors of each variable. The constellation graph can simultaneously grasp both the tendencies of the objects and 𝑝 -dimensional variables. In the expanded kanji graph, the height and width of the kanji are determined using the mean values of the variables for each cluster. The kanjis are placed around the radar chart drawn using the standard deviation. The kanji graph can intuitively grasp the characteristics of each group in the cluster analysis. Herein, the effectiveness of the proposed methods is verified by evaluating the flavor of whiskey. The proposed methods show that whiskey flavors can be classified into five clusters: (1) “full-body and winey type,” (2) “sweet and balanced type,” (3) “smoky and balanced type,” (4) “full-body and smoky type,” and (5) “light-body and sweet floral type.”
